示例性的，本申请实施例提供的电子设备不仅根据温度传感器提供的电池温度，还根据电子设备的环境温度，对电子设备是否处于低温环境进行检测，可及时检测到电子设备处于低温环境，从而避免了传统电子设备低温保护中仅依靠温度传感器检测到的电池温度来进行电子设备低温保护所存在的滞后问题，同时也解决了在电子设备中设置多个温度传感器导致的结构复杂成本较高的问题，本申请提供的电子设备低温保护方法具有较好的低温保护效果。
下面采用具体实施例，对电子设备实现低温保护的过程进行详细说明。本申请以下实施例中至少提供了一种电子设备低温保护方法和电子设备。下面这几个具体的实施例中，对于相同或相似的概念或过程可能在某些实施例不再赘述。
本申请实施例一方面提供一种电子设备低温保护方法。图2为本申请实施例一提供的电子设备低温保护方法的流程示意图。本申请实施例提供的电子设备低温保护方法根据温度传感器提供的电池温度以及电子设备的环境温度来确定电子设备是否处于低温环境，并在处于低温环境时对电子设备进行低温保护，本申请提供的电子设备低温保护更及时。本 实施例提供的电子设备低温保护方法的执行主体可以为图1中的电子设备。如图2所示，电子设备低温保护方法包括：
S201、电子设备获取环境温度和电子设备的电池温度。
示例性的，电子设备实时或按预设周期获取环境温度和电池温度。
其中，电池温度为温度测量设备实时或按照预设周期测量得到的电池的温度。可选的，电子设备获取电池温度的方式可以为：获取电子设备中温度传感器所采集的温度。可选的，电池温度还可以为其他温度测量装置直接或检测测量电池得到的温度，本申请对此不作限定。可以理解的是，电子设备可以直接接收温度传感器所采集的温度，还可接收温度传感器所采集的数值，然后获取该数据对应的温度。
示例性的，电池温度可以由设置在电池的保护板上的温度传感器获得，高于电池的内芯温度。当根据电池温度对电子设备进行温度保护时，可以及时的检测到电子设备中的电池是否处于高温环境，但是无法及时检测到电子设备中的电池是否处于低温环境，对于电子设备的低温保护存在滞后，即当根据电池温度确认电子设备处于低温环境时，电池的内芯早已处于低温环境。
本实施例中，在获取电池温度的同时还获取电子设备的环境温度。电子设备的环境温度可以为电子设备所处环境的温度。由于电池在使用时存在发热等情况，因此电子设备的环境温度通常低于电池的内芯温度。因此当根据电子设备的环境温度对电子设备进行温度保护时，可以及时的检测到电子设备是否处于低温环境。
可选的，一种可能的获取环境温度的方式可以为：
根据电子设备的系统参数和预设映射关系，电子设备确定环境温度。
其中，预设映射关系指示系统参数所对应的环境温度。
示例性的，电子设备中存储有预设映射关系，预设映射关系指示了电子设备的系统参数为不同取值组合时，电子设备的环境温度。该预设映射关系可以在电子设备出厂前通过测试统计得到，并在电子设备出厂时配置在电子设备中。当电子设备为可通信设备时，电子设备还可通过网络更新该预设映射关系。
在电子设备中存储有预设映射关系时，可根据获取到的电子设备的系统参数，查找该预设映射关系，从而确定出电子设备的环境温度。
可选的，上述获取环境温度的方式中电子设备的系统参数包括下述至少一项：
电子设备的显示屏功率、电子设备的显示屏亮度、电子设备的功耗、和/或电池的温度传感器所采集的温度。
示例性的，电子设备的系统参数还包括电子设备中应用的运行情况，电子设备中处理器和内存的使用情况，以及电子设备是否设置有外壳以及外壳材质等信息。
可选的，另一种可能的获取环境温度的方式可以为：
获取电子设备所在地理位置的气温信息作为环境温度。
示例性的，当电子设备为手机、平板电脑等可联网设备，可通过网络查询电子设备所在的地理位的当前气温信息，作为环境温度。还可通过电子设备上已有的天气应用提供的气温信息作为环境温度。
可选的，再一种可能的获取环境温度的方式可以为：

示例性的，电子设备管理管理房间内的空调、智能扫地机、冰箱、监控等智能家电设备。
S202、根据环境温度和电池温度，电子设备确定处于低温环境。
示例性的，本申请实施例中考虑到根据电池温度进行低温检测时存在滞后的问题，而电子设备的环境温度通常低于电池的内芯温度，基于电子设备的环境温度可敏感的检测到电子设备是否处于低温环境，因此，本申请实施例中根据环境温度和电池温度对电子设备是否处于低温环境进行检测，可避免仅根据电池的温度进行低温检测存在的滞后问题，提高了电子设备的低温检测的准确性，避免了低温环境下电池性能降低对用户使用电子设备的影响。
示例性的，在根据环境温度和电池温度确定电子设备是否处于低温环境时，可同时或先后比较两个温度与预设温度，与两个温度进行比较的预设温度可以相同，也可以不同。还可根据环境温度和电池温度的不同取值组合，查找低温映射表，确定该取值组合下的电子设备是否处于低温环境。低温映射表指示了不同温度取值组合下电子设备所处的温度状态，电子设备的温度状态可以有高温环境、正常温度环境和低温环境。
S203、响应于所确定的处于低温环境，电子设备实施低温保护。
示例性的，当检测到电子设备处于低温环境时，立即实施对电子设备的低温保护，执行低温保护措施，避免电池在低温下工作，电子设备无法正常响应用户的指示，影响用户对电子设备的使用感受。
可选的，电子设备的低温保护措施可以包括：
调节电子设备中至少一个器件的工作电压；和/或
调节电子设备中至少一个器件的工作电流；和/或
关闭电子设备中至少一个正在工作的功能；和/或
关闭电子设备中运行的至少一个应用程序。
具体的，在对电子设备进行低温保护时，可调节电子设备中的至少一个器件的工作电压，当电子设备温度较低，可降低电子设备中的器件的工作电压，降低电子设备功耗，避免电子设备在低温环境下关机，影响用户使用电子设备。示例性的，参照调节工作电压的方式，还可调节电子设备中至少一个器件的工作电流。可选的，还可关闭电子设备中正在工作的至少一个功能，例如，根据电子设备中的各功能工作时的发热能力或功耗的不同，在电子设备处于低温环境时，选择关闭一个或多个功能，避免电子设备在低温环境下关机。例如，当电子设备为手机时，可选择关闭摄像头的拍照、视频功能、摄像头拍照时的的闪光灯功能、手电筒功能等。可选的，还可关闭电子设备中运行的至少一个应用程序，例如，当运行的应用程序较多时，可选择关闭运行在后台的用户当前并未使用的应用程序，以减少功耗。
可选的，在进行低温保护时，可将上述多种温度调节方式相互结合使用。
本实施例提供的电子设备低温保护方法，包括：电子设备获取环境温度和电子设备的电池温度；根据环境温度和电池温度，电子设备确定处于低温环境；响应于所确定的处于低温环境，电子设备实施低温保护。本申请实施例中考虑到传统电子设备温度保护方法中根据电池的温度进行低温检测时存在滞后的问题，而电子设备的环境温度通常低于电池的内芯温度，基于电子设备的环境温度可敏感的检测到电子设备是否处于低温环境，因此， 相比仅根据电池温度对电子设备进行温度保护，同时考虑了环境温度和电池温度，根据环境温度和电池温度对电子设备是否处于低温状态进行检测，可避免仅根据电池的温度进行低温环境检测存在的滞后问题，提高了电子设备的低温环境检测的准确性，避免了低温环境下电池性能降低对用户使用电子设备的影响。
示例性的，在图2所示实施例的基础上，本申请实施例提供的电子设备低温保护方法中，为提高电子设备低温环境检测效率，可首先检测环境温度或电池温度是否小于一预设温度，该预设温度为一高于电池的最低工作温度的温度值。当检测到环境温度或电池温度不小于该预设温度时，则无需进行更进一步的温度检测。当检测到环境温度或电池温度确实小于该预设温度时，则需进一步进行更多的温度比较确定电子设备是否处于低温环境。其中，环境温度和电池温度可以各自对应不同的预设温度。
示例性的，环境温度和电池温度对应相同的预设温度时，当首先比较电池温度与对应的预设温度时，电子设备低温环境检测的可靠性较高；当首先比较环境温度与对应的预设温度时，电子设备低温环境检测的灵敏度较高。这是由于同一电子设备的电池温度通常高于环境温度，环境温度相比电池温度会更早的接近预设温度，并更早的触发下一步的电子设备低温环境检测。通过将电子设备低温环境检测划分为两层，可提高电子设备低温环境检测的效率，提高电子设备低温保护的及时性。
